+- [Detector benchmarks](https://eicweb.phy.anl.gov/EIC/benchmarks/detector_benchmarks) - Set of analysis scripts  run on the Geant4 output before any digitization or reconstruction. Also contains some detector calibrations.
+- [Reconstruction benchmarks](https://eicweb.phy.anl.gov/EIC/benchmarks/reconstruction_benchmarks) - Analysis of the many aspects of reconstruction. This is where the tracking performance benchmarks and plots live. Also a good place for developing new algorithms.
+- [Physics benchmarks](https://eicweb.phy.anl.gov/EIC/benchmarks/physics_benchmarks) - Analysis of reconstructed for physics performance.  The goal is to provide metrics for optimizing detector design and reconstruction.
